Question: A granite column in a building is 8.00 m high and has a mass of 2.16 104 kg. (a) How much heat (in J) is needed to increase its temperature by 9.5°C, given its specific heat is 0.200 kcal/kg·°C? J (b) What is its change in length (in m) if its coefficient of linear expansion is 2.50 10−6/°C? m (c) Calculate the force (in N) it
For example, a 35-year-old, 200-pound (90.7-kg), 6-foot (183-cm) male would have a BMR/RMR of 1,882. At rest, he'll burn around 1,882 calories in a day.Women who breastfeed require approximately 500 additional kcal/day beyond what is recommended for non-pregnant women. 68 The estimate is derived from the mean volume of breast milk produced per day (mean 780 mL, range 450-1200 mL) and the energy content of milk (67 kcal/100 mL). 69 During pregnancy, most women store an extra 2 to 5 kg (19,000
A granite column in a building is 8.00 m high and has a mass of 2.16 x 104 kg. (a) How much heat (in )) is needed to increase its temperature by 10.0°C, given its specific heat is 0.200 kcal/kg.°C? (b) What is its change in length (in m) if its coefficient of linear expansion is 2.50 x 10-6°C?To determine calories expended by your favorite activity use the following equation: METS X 3.5 X BW (KG) / 200 = KCAL/MIN. For example, if a 30-year-old man weighing 170lbs (77.3kg) performs 45 minutes of running at 7mph, the amount of calories he would burn per minute would be: 11.5 (3.5) (77.3kg)/200 = 15.6 kcals/min.
